Specification of Letters Patent.

Patented July 9, 1912.

Application filed June 12, 1906. Serial No. 321,378.

To all wfiom it may concern:

Be it known that I, HORACE CHRISMAN, a citizen of the United States, anda resident of Edgewood, in the county of Allegheny improved arrangementand combination of parts is utilized.

This and other objects I attain in a meter embodying the features hereindescribed and illustrated in the several sheets of drawings accompanyingthis application and forming a part thereof.

Figure 1 is a vertical section along the broken line A A of Fig. 2; Fig.2 is a plan view of the meter shown in Fig. 1, a portion having beenremoved for convenience of illustration; Fig. 3 is a vertical section,corresponding to the section in Fig. 1, of a modification of myinvention} and Fig. 4 is' a partial section along the line B-B of Fig.3.

Referring to Figs. 1 and 2: The meter casing consists of a bottomportion .5 and a top portion 6 secured to the bottom portion by bolts 7,and which carries an indicating apparatus 8. The bottom portion isprovided with a liquid inlet port (not shown), which communicates,through a passage 9,

Y with a chamber 10, located centrally within .the meter casing. A wingwheel casingll I is located in the chamber 10 and a discharge port 12,formed in the lower portion 5 of the casing, communicates therewiththrough a passage 13. The wing wheel casing con sists of a cylindricalportion 14, a bottom portion 15, integrally formed therewith, and aremovable top portion 16-. The cylindrical portion 14 .is provided withintegrally formed annular flanges 17 and 18 which are supported bysuitable surfaces located on the walls of the bottom portion 5.

The flanges 17 and 18 are so arran ed that an annular passage 19 isformed e- .tween the cylindrical portion 14 and a wall 21 of the metercasing, and the wheel casing 11 is rigidly locked in position when'thetop portion 6' of the meter casing is secured in place.

. The wall 14 of the casing 11 is provided with a suitable number ofports 22, which extend therethrough and are a means of communicationbetween the passage 19 and the interior of the wheel casing.

A wing wheel 23 is provided with a suitable number of radially-extendingblades 24 and is mounted-within the casing 11 on a verticalsp'indle 25.The spindle 25 is provided with an adjustable step bearing 26 supportedby a conical hub portion 27 formed integrally with the bottom portion15. The hub portion 27 is provided with a conoidal trumpet orcone-shaped flange 28, between which and the bottom portion 15 a' numberof integrally-formed vertically-disposed radial webs 29 are interposed.

The top portion'16 is provided with an integrally-formed hub portion 31similar to the hub portion 27, and throughwhich the vertical spindle 25extends. -A conical flange 32, integrally formed with the hub portion31, and integrally-formed webs 33,

whichcorrespond in position and location to the webs 29 of the bottomportion 15, are provided between it and the top portion 16. The topportion 16 is adapted to be secured to the cylindrical portion 14' byscrews 34.

The conoidal flanges 28 and 32 of the bottom and top portions,respectively, cooper ate with the flanges 17 and 18 of the cylink dricalportion 14 to form annular passages, which communicate with ports 35 and36, formed in the bottom and top portions respectively. The ports 35 and36 communicate with the passage'13 through the above mentioned annularpassages, formed by the flanges 17 and 18 and the flanges 28 and 32.

Radially-extending vertically-disposed retarding vanes 37 are mounted onthe bottom portion 15 within the casing 11 adjacent to the ports 35 andretarding vanes 38, similarly located with reference. to the ports 36,

are mounted on' the top portion 16 within the inlet portof the metercasing mustpass through the ports 22 of the cylindrical portion 14, theinterior of the wheel casing 11 andthe ports or 36 of the casing 11,before it is discharged through the discharge port 12. The baflle plate41 gives to the water passing through the passage 19 a whirling motionwhich tends to overcome its tendency to enter-the orts 22 of thecylindrical portion 14, which are located directly opposite to theadmission passage 9.

The ports 22 of the cylindrical portion 14 are so positionedand'arranged that the water passing through them and enteringtheinterior of the casing 11 is caused to impinge upon the blades 24 ofthe wing wheel 23 and cause it to revolve in a direction indicated bythe arrow in .Fig. 4. The ports 35 and 36 are of such area, relative totheinlet ports 22, that the water in passing through the interior of thewheel casing 11 is divided, a portion being dischargedthrough the ports35 'n the bottom portion,

and .a portionthrougi the ports 36 in the top portion of. the casing,thus maintaining a balance on thepropeller 23. i I

The retarding vanes 37 and 38 are so positioned and arranged that theycauseeddy currents within the casing 11 during the operation of themeter, which tend to retard the wheel. Under ordinary conditions thewheel tends to-move faster in proportion to I the amount of waterpassingthr'ough the meter, for heavy flows than for light flows, sincethe retarding resistance, which is the mechanical inefiiciency of theapparatus, remains constant, but the accelerating force increases as theflow of water through the meter increases. With the retarding vanespositioned as'illustrated, the effect of the eddy currents increasesapproximately in direct proportion to the increase of flow.

through the meter, and consequently the retarding force increases withthe wing wheel accelerating force and the tendencyof the indicatingapparatus to over register for heavy flows'is overcome. v

A modification of my invention is shown in Figs. 3 and 4. The wing wheel23, which, as before, is mounted on a spindle,25, is lo,- cated within awheel casing which comprises a cylindrical portion '14 with a bottomportion 15 and a removable top portion .16, formed substantially in thesame manner as in Fig. 1. The annular flange 28 of the 'hub portion 27,however, is extended into a cylindrical shell 42, which is integrally,

formed with an annular flange 18 of the CYllIldIlCftl portion '14. Thewater entering the interior of the wheel casing traverses passages 43,,formed between the shell portions 11 and 42, and which communicates withthe inlet ports 22.. ,By this arrangement the water discharged from theinterior of the wheel casingthrough the ports paratus shown isonly'illustrative and that the invention can be carried out by othermeans.

What I claim is:

1. In a water meter, a wheel casing pro-1 'vided with outlet ports'andperipherally disposed inlet ports, a wingfwheel located between theoutlet ports and conoidal deflectors arranged on opposite sides of said.

wheel and adjacent to said outlet ports.
